This datasheet also covers the SC1 variant, as both devices belong to the same power supply controller for portable pentium ii & iii speedstep processors family and are provided as variant models within a single manufacturer datasheet.
General Description
The SC1406G PowerStep controller is a High Speed, High Performance Hysteretic Mode PWM controller.
Teamed with the SC1405 Smart Driver, it powers advanced Pentium® II and Pentium® III processors.
Key Features
Intel Mobile Voltage Positioning (IMVP), which increases battery life by reducing the voltage at the processor when it is heavily loaded. It also directly supports Intels SpeedStep processors for even longer battery life. A 5-bit DAC, accurate to 0.85%, sets the output voltage reference, and implements the 0.925V to 2.00V range of the mobile Pentium® specifications. The hysteretic converter uses a comparator without an error amplifier, and therefore provides the fastest possible transient resp.
